bile drivers in endeavoring to start the engine in cold weather. This of course is caused by the cool condition of the engine and the fuel passages leading thereto which results in the inability to vaporize or gasify the liquid fuel.

It is the object of this invention to provide means for heating and hence vaporizing liquid fuel in its passage to the engine cylinder which will be as effective in cold weather as in warm and hence whereby the engine may be readily started irrespective of the outside temperature.

A further object is the production of a derice as mentioned which will be of simple andeconomical construction and eflicient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which- Figure 1 is a front elevation'of a conventional intake pipe of an explosion engine equipped with a vaporizing device embodying our invention, Fig. 2 is an enlarged section taken on substantially line ww of Fig. 1, and Fig. 3 is a section taken on substantially line g y of Fig. 2.

The preferred form of construction as illustrated in the drawing comprises a holder or body 1 preferably of the form and proportions shown. Arranged centrally in the member 1 is a ring 2 of noncombustible material, metal being preferably used which is removabiy secured in position in the member l by means of insulating material 3. side of the member 1 is recessed, as

clearly shown in Fig. 3, to accommodate the ring 2, the insulating material 3 serving to efl'ectually insulate said ring of said holder- In the event of the holder being itself formed of insulating material it will of course be unnecessary toinsulate the ring 2 therefrom, the insulation of said ring from said holder being resorted to only when the latter is formed of a conducting material.

Arranged in the ring 2 is a heating element 4 formed of a band or strip of material of high electrical resistance. The member 4 is bent upon itself in a tortuous manner as shown so as to form a. plurality of parallel spaced blades which traverse the passage or opening through themember 2.

Said blades are preferably inclined, as clearly shown in Figs. 2 and 3, so as to in crease the traversing effect thereof in the passage or opening in the member 2 while, at the same time, passage of fluid through said member will be unimpeded and unob- .struc ted. Said element 4 is insulated from ring 2 as illustrated, this insulation being however unnecessary if said member 2 is tening devices 8. The arrangement is such that the opening through the member 2 will coincide with the passage through said intake pipe and so that element 4 will be interposed in said passage. This being so upon the passage of current from the source of electrical energy 6 through said element 4 which, because, of the high electrical resisting character of the latter causes heating thereof, the liquid fuel passing through said intake pipe will contact with or impinge upon said element and thereby become heated and hence vaporized or conditioned for ignition. Through the inclination of the traversing fluid portions of the heating element 4, the contact of ail particles of the liquid fuel passing through the pipe 7 with said element is insured thereby resulting in the thorough heating of the fuel with the corresponding advantageous result in the ignition of the mixture as will be appreciated by those skilled in the art.

The device is of extremely simple con- I struction and hence may be manufactured at a low cost. The component parts of the device are so connected that, in the'event of one or more of said parts becoming disabled or worn out the same may be removed and replaced without destroying the remaining parts thereof.

While we have illustrated and described the preferred form of construction for earrying our invention into efi'ect, thi is capable of variation and modification without departing from the spirit of the invention. \Ve, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and modifications as come Within the scope of the appended claims.

Having described our invention. what we claim as new and desire to secure by Letters Patent is:

1. The combination with a fluid passage, of means for heating the fluid passing through said passage, said means comprising an element of high electricalresistance consisting of a plurality of substantially parallel spaced blades obliquely disposed in transverse arrangement interposed in and traversing said passage, said blades being connected together to form a continuous electrical conductor; and a source of electrical energy connected with said element for passing an electrical current therethrough', substantially as described.

2. The combination with a fluid passage,

of means for heating the fluid passing HOMER H. INGERSOLL. CLARENCE B. INGERSOLL.
